Well instead of giving you the answer, lets look at how to create a method with a void return type. 

- (void) thisMethodIsATest {
       NSLog(@"Test");
}

Notice that the - (void) section of the method denotes it as a voided method, or a method without a return type.

I hope this helps :)

(IBAction)button:(id)sender { }

  • It takes in the sender ( basically whoever triggered the method)
  • It returns IBAction ( the type of action that took place e.g touch up inside)
